Contingent Liability Where we effect or arrange a Transaction, you should note that, depending upon the nature of the Transaction, you may be liable to make further payments when the Transaction fails to be completed or upon the earlier settlement or closing out of your position. You may be required to make further variable payments by way of margin against the purchase price of the investment, instead of paying (or receiving) the whole purchase (or sale) price immediately. The movement in the market price of your investment will affect the amount of margin payment you will be required to make. We will monitor your margin requirements on a daily basis and we will inform you as soon as it is reasonably practicable of the amount of any margin payment required under this clause.
